Ed's place is clean and comfortable:) he was really helpful and understanding throughout as well. The place has a washing machine and dryer and many electrical appliances thoughtfully prepared for guests.
Nana is close to many areas like thonglor and siam but do note this is in the red light district of bangkok. As 2 females heading home, we didn't feel unsafe but this might be something for you to consider. That being said, it is a very good anchor location to other places and there was no noise that travelled to Ed's apartment!
